When you activate the windshield washer fluid to spray over your windshield, the washer pump emits a characteristic sound. When you press the button, if no sound is made and no fluid sprays over your windshield, the pump is either damaged or isn’t getting electricity. If this is the situation, make sure the fuse that powers the washer pump isn’t burned out and replace it if it is. To replace the windshield washer pump, though, you’ll need to get in touch with a nearby ASE-certified mechanic if the fuse is not the issue.

How much does a new window washer pump cost?
Best in Automotive Repair Replacement windshield washer pumps typically cost between $122 and $163. Between $74 and $94 is the expected range for labor costs, whereas $48 to $70 is the range for part prices. Taxes and other costs are not included in this range, nor are your particular vehicle or geographic area taken into account.
Where is the pump for the windshield wiper fluid?
The windshield washer pump and a small electric motor are packaged together in contemporary autos. The windshield washer pump is often mounted in the tank’s lower section (bottle).
The windshield washer fluid tank’s bottom holds the windshield washer pump (motor).
As seen in the figure, the windshield washer tank is often found in front of one of the front wheels, behind the front bumper.
How it works: When you turn on the washer using the switch, the control module (like the BCM) receives a signal. The control module uses the relay to turn on the windshield washer pump. Through the hoses that are attached to the washer jets, the pump pumps windshield washer fluid.
Why does the pump for windshield washers stop working?
Disconnect the connector at the pump and use a volt meter to check for power if the fuse is sound but the pump won’t operate.
- It must show 12 volts when the washer switch is turned on. Faulty electrical connections at the pump or a defective pump are typically at blame if you can’t hear the pump and the fuse is functioning properly.
As you check for 12 volts with a digital meter at the connector, unplug the pump wire connector and let a friend operate the pump switch.
- If you don’t have voltage, the washer switch or the wiring are probably the cause. Take the car to a mechanic at that point.
- Clean the terminals and apply dielectric silicone grease if there is voltage.
Retry using the pump. If it succeeds, your issue is resolved. If not, you should swap out the pump. The motor being operated continuously while the reservoir is empty is the main reason why pumps fail. In order to avoid having to deal with replacing a bad reservoir, strive to keep it full.
What causes failure of the pressure washer pump?
Even while you are not spraying, the pressure washer pump continues to create pressure. The pressure created by the pump does not release when you release the trigger; instead, it continues to increase. Unrelieved pressure has no negative effects on the pump. This is due to the unloader valve, also known as the thermal release valve, activating when the trigger is not squeezed for a while. The water flow is changed by the unloader valve to go in a loop to the inlet. In the bypass intake, the pressurized water is depressurized before being delivered once more to the pump. Until the water is discharged, this cycle is continued.
The unloader valve’s bypass system defends the pump. You shouldn’t push it over its breaking point though. When the pump is in bypass mode for too long, overheating occurs. The same water warms up as it circulates through the pump due to heat produced by the crankcase. The pressure washer’s pump may be harmed if this water overheats. Although the water can cycle in bypass for up to 2 minutes according to the manufacturers, we advise against leaving your pressure washer running for longer than 45 seconds without squeezing the nozzle. The washer must be shut off and restarted when you are ready to use it if you need to wait longer than that for some reason.
A defective unloader valve and a blocked carburetor are the two most frequent causes of the pressure washer pump failing (in the case of gas-powered washers).
Diagnosing the Sprayer Nozzles
Verify the washer’s liquid level.
Verify that there is washer fluid in the reservoir for the windshield wipers, and add more if necessary.
Cut the washer fluid hose off.
The washer fluid hose should be located, disconnected, and placed to the side in a position to release fluid if the nozzle or sprayer does not spray fluid while the tank is fully stocked with washer fluid.
Check for leaks in the washer fluid hose.
Press the washer fluid button while the hose is not attached to the washer fluid tank to observe if fluid comes out of the hose. If fluid leaks, the issue is deeper within the system. If there is no fluid escaping, the hose is either broken or the fluid inside the hose is frozen.
Examine the sprayer nozzles
Apply an air nozzle to the hose leading to the sprayer nozzle to inject air into the nozzles. The hose is clear if fluid pours out of the nozzles, and it may also clean the lines of any impurities like dirt or ice. The hose may be broken or clogged if the fluid does not spray out of the nozzles.
Look over the Sprayer Nozzle Hose Line.
Pull back the shield under the hood cover and check the hoses for looseness, damage like tearing, or any disconnections from the nozzle if, after doing this test, washer fluid did not exit the nozzle.
A washing pump costs how much?
A new washer pump is the component that is most crucial. The price range is between $10 and more than $75. But the average cost of a replacement pump for households is between $25 and $40.
What is the price of a windshield washer motor?
The cost to replace a windshield wiper motor ranges from $250 to $300 on average. The majority of the cost will be made up of the parts, which range in price from $200 to $250. However, most automobiles just require a simple installation, so your labor costs will only be $50 to $100.
Look for other less expensive parts that could be the root of your issue before replacing the windshield wiper motor. For instance, a blown fuse that simply takes a few dollars to fix can make the wipers stop working.
If the windshield wiper motor does need to be replaced, think about performing the straightforward task yourself. Your wipers can be fixed with some simple tools in a short amount of time.
Why won’t my window washers operate?
Windscreen washer pumps may experience issues that limit how efficiently the washers function or prevent them from spraying at all. Common examples include:
Dirt in the Nozzles
Clogged washer nozzles are one of the most frequent causes of screenwash problems. This occurs when tiny dust and dirt particles enter the nozzles that are affixed to the top of the bonnet and block the spray from functioning.
To clear the obstruction, poke about within the nozzles with a safety pin or needle. To completely eliminate the obstruction, you might need to spray the screenwash a few times.
Clogged Washer Feed Tubes
The feed tubes connecting the reservoir to the nozzles can occasionally become clogged with dirt and other debris. Intermittent screenwashing or a complete lack of it altogether are signs of a clogged washer hose.
Start by removing the hoses from the windshield washer reservoir. You’ll need a screwdriver to free them up because clamps and a rubber grommet are holding them in place. After that, use an airline or a can of pressurized air to spray down the nozzle and drive the particles out of the washer hose’s end. Avoid washing down the hose towards the nozzles; doing so may force dirt and debris into the nozzle head, making it more difficult to clean.
Faulty Windscreen Washer Pump
If your washer still performs poorly after you’ve cleaned the nozzles and hoses, there might be an issue with the pump. The steps to troubleshoot and identify a windscreen washer pump are as follows:
- Turn off the power and reach the washer reservoir’s bottom if the pump isn’t functioning. The problem might be caused by soiled electrical connections, in which case a quick clean would be sufficient.
- You might need to replace the fuse, which is a fairly simple procedure, if there is no electricity. Simply locate the fuse box using your manual, then swap out the washer pump fuse with a fresh one.
- While you put your hand on the reservoir, have someone else turn on the washers inside the car. Check to see if you can feel any vibrations when the switch is turned on and listen for the pump to start buzzing. If you can, there’s probably a clog or a leak from the reservoir; if you can’t, the pump is broken.
- If not, you’ll need to remove the reservoir casing’s two screws that typically hold the motor and pump to it. After doing this, restart the ignition and check with an electrical tester that the pump and motor are receiving electricity.
- Replace the windscreen washer pump if there is electricity; we’ll explain you how to accomplish this below.
Is it worthwhile to replace the pressure washer’s pump?
There are numerous methods to burn out pressure washer pumps. It happens more frequently than you might think.
Pressure wash pumps burn out and break occasionally, whether it was because you left the pump running with no pressure release, it cracked while being stored during the off-season, or perhaps it was simply the result of wear and use.
But you don’t have to replace your pressure washer and buy a new one. Simply replace your pressure washer pump instead.
Warning:
Read the owner’s manual for your pressure washer and any other documentation that came with the replacement pump in its entirety before starting the removal and replacement of your pressure washer pump.
Always use caution while working with power tools, and before starting the pressure washer pump replacement operation, make sure the pressure washer is unplugged from any power sources or that the spark plug has been taken out.
How durable are pressure washer pumps?
In average, a decent pressure washer pump should last 5 to 10 years when utilized properly. Some inexpensive pumps can last considerably less time. Avoid overheating, cavitation, and using your pump with the incorrect unloader valve settings to get the most out of it.
The lifespan of a pressure washer pump is influenced by a variety of factors. The material used in pumps is the most crucial. Each pump manufacturer has unique manufacturing criteria, which typically match the cost. The life of the pressure washer pump will be extended by using better materials and smaller manufacturing tolerances.
Some of the cheaper pumps have a lifespan of up to 100 hours. Your pressure washer will last two years if you use it 50 hours each year. This number will rise if you use your PC less frequently. How you utilize and take care of the pump will dramatically affect how long it lasts. The figures serve as additional cues, and it’s entirely feasible that a cheap pump lasts much longer.
The pressure is a significant additional aspect that influences a pressure washer pump’s lifespan. Pressure washers with persistent demand for the greatest pressures have a shorter lifespan. It’s comparable to your car. If you drive your car at full blast, the engine will malfunction more quickly.
